OVEN YANEL.

To all wwmz't may cof/wem.

Be it known that I, Grenen A. YOUNG, a

vcitizen of the United States of America, re-` siding at Detroit,'in the county of Wayney and State kof Michigan, have invented certain new and useful Improvements in Oven Panels, of which the following is a s ecification, reference being had therein to tiie accompanying drawings.

This invention relates to oven panels and has special reference to insulating panels that may be used as doors, partitions and walls of ovens and other structures, and the invention relates to that class of panels which are fabricated from metal and insuy lation material in contradistinction toinsulating wall boards or blocks devoid of enclosures.

One of the objects of my invention is to provide a metallic panel t at can be filled with a powdered or granular insulating material and such material maintained in placey without .any danger of the material settling, f

packing or becoming displaced tothe extent of forming crevices or air pockets which would reduce the insulating characteristics of the anel.

Anot er object of this invention is to furnish a hollow metallic panel with interior reinforcing members that will serve two purposes; nst, that of bracing and lending rigidity to the walls of the panel, and second, that of providing interior shelves or supports for insulating material within the panel. The arrangement of shelves or supports is such that they do not interfere with a continuous insulation of the panel from one end thereof to the other end from one sideto the other and in all directions, nor does the arrangement interfere with equal distribution of the insulation. material` panel will be hereinafter specifically descrlbed and then claimed.

Reference will now be had to the drawing,

front and rear walls'l and 2, top and bottom f walls 3 and. 4, and side walls 5, the walls 3, 4. and beingy channel shaped in cross section with the flan es G'thereof outstanding against the inner faces of the walls 1 and 2 so that the marginal edges of the walls 1 and 2 may be inturned over the flanges 6 and spot welded or otherwiseconnected to said anges All the walls cooperate in forming a flat rectangular enclosure or cas- 1ng, and the side walls v5 may be reinforced agalnst buckling, by lates 7 set against the inner faces of the wa ls. In many instances 1t 1s not necessary to use such reinforcing plates. l

The top and bottom walls 3 and 4, inter` i mediatethe ends'thereof maybe provided angle bars 9 having short flanges secure the walls`1 and'2 and long flanges projecting into the space between the walls land 2 to serve functionally as shelves or supports within the casing or enclosurev formed by the walls 1 to 5' inclusive.

In the panel casing or enclosure is laced an insulating material 10. This insu ating material is preferably powdered or granular in order that raw material, lent'iful and practically waste, may be use ,and we use one hundred per cent of this material in eontradistinction to insulating blocks or fillers using about seventy-five per cent insulating material, and the remainder lime and asbestos fibre or other binders. The powdered or granular insulating' material is compressed in the anel enclosure to provide a solid, more or ess homo eneous mass within the panel. The insulatin material being compressed about the angle ars 9 pro* vides an insulation throu hout the panel for the reason that the angle ars are staggered, do not contact, and afford a sinuous insulating path from one end of the panel to the other. When the panel is used in a vertical position there is no danger of the insulating material settling or packing in the bottom of the panel, which has been the objectionable feature of insulating powder for oven panels.

I do not care to confine m3' invention, unless necessary, to a powdere insulating material as a lastic insulating material ma be em loyed), for instance a material that could poured into the panel through'a suitable opening to harden within the panel and exclude air from the panel. Therefore one embodiment of my invention has been described, but it is to be understood that changes may be made without departing from the scope of the appended claims.

What I claim is 1. A. panel of the class described, comprising a metallic enclosure having o posed flat walls, an insulating material within said enclosure, and means on the flat o posed walls of said enclosure and alternate y disposed therein for reventing settling or packin of the insu ating material in one part o said enclosure.

2. A panel of the class described, com prising a metallic enclosure, inwardly ro- ]ecting sup orts carried by walls of sai enclosure wit the supports of one wall s aced from the supports of an adjacent wal and a homogeneous mass of insulating material in said metallic enclosure on and between the supports therein.

3. An oven panel comprising metallic y walls forming an enclosure, reinforcing members on the inner faces of some of sai walls with some of said reinforcing members servin as supports, said reinforcing members a Ording a sinuous space from one end of said panel to the opposite end thereof, and insulating material in the sinuous space of said panel and on the reinforcing members serving as supports.

In testimony whereof I aiiix m signature.
